Atually Renault had rather long wheelbase already in 2005. McLaren extended their wheelbase for 2007 (easy to spot the difference visually) etc.

no data on McLaren unfortunately.

Thanks for the data. All this wheelbase talk has got me going 'round in circles.

The F2007 does NOT have an EXTRAORDINARILY long wheelbase. What it does have is a wheelbase longer than the F248; they felt they had something good with the relatively short wheel base of the F2003 GA, and stuck to it up to 2006. This "return" to the "longer" wheelbase, being somewhat a major design change, started all this long wheelbase talk.

Again, the F2007's wheelbase isn't specially long. I mean Honda's got 5mm on them. It means nothing on track, but it's still longer.

Yes but maybe McLaren has a very short wheelbase.
The Ferrari performance was quite normal, Massa was faster than
all the others and Kimi only stuck in traffic.

The speed of McLaren was not normal.
They where extremly fast.
And they are even fast in Monaco when they have a bad year.

So we have to look what is different at the McLaren cars.

With knowing now that a longer wheelbase can cause 1 degree
more steering angle we should look now on a graph for slip
angle and grip to see how much grip can be lost here.

Has anyone some good graphs wich are similar to the F1 tyres.

Look at the pic above. It's longer than one of MP4-21

they are several other factors that would have helped mclaren go slightly faster ....we dont know all of them, i wish i was a mclaren engineer to know all of these ...

(please note that these are just numbers from the net, I cannot be sure if they are correct)
I googled around for McLarens wheelbase and this is what I got:
MP4-1: 2642
MP4-1b: 2692
MP4-1c: 2682
MP4-2: 2794
MP4-3: 2768
MP4-5: 2896
MP4-5b: 2940
MP4-6: 2960
MP4-7: 2960
MP4-8: 2845
MP4-9: 2845
MP4-10: 2860
MP4-11: 2990

MP4-14: 3070
MP4-15: 3145
MP4-16: 3074
MP4-17: 3162

Couldn't find any numbers for the latest, just a mention that the wheelbase of MP4-22 is longer than on MP4-21 and MP4-20 has shorter wheelbase than MP4-19.

The older version could develop more downforce than the current ones ...

Oh, and let's not forget the ban on flexing floors... that could affect Ferrari somehow. Not that I'm betting on that. Supposedly Monaco was the place where the influence of this ban would be less.

Wasn't that banned before Spain?

just like others (including the shorter-base F2002)
